I've had two fish get the black head, one was a boesmani, which had only
the right side of the head go black, and lived like that seemingly
otherwise well for over a year. No other fish in the tank showed any signs
of ill health. That was about 5-6 years ago.
The other fish got a more completely black head, and died after a couple of
months. This was about a year after the first fish died. Unfortunately my
memory is not good on what it was, I keep changing my mind on the species,
but I'm sure it wasn't a tri, and I'm pretty sure it was an Australian
fish.
Incidentally, both were in the same tank.
